This potion inhabits a heavy vial, and rapidly shift between a deep ruby-red and a vibrant emerald-green. 

Using an action, a creature may throw this heavy vial up to 30ft and speak one of two command words: Healing or Boom. When the potion lands roll a d6, on a 1-5 the vial goes off without a hitch; however on a 6 the magic contained within the vial backfires and acts as if the opposite command word was spoken. 

Healing - Using this command word causes all creatures within 10ft of the point of impact to regain 14 (4d4+4) health. The effect of this potion leaves the smell of lilacs in the air, and somehow the taste of cherries on all affected creature's tongues. 

Boom - Using this command word causes the emerald-green color within the potion to glow brighter. Upon impact a shower of explosive sparks leap out from the vial. All creatures within 10ft of the point of origin must make a DC 12 dexterity saving throw, taking 14 (4d4+4) piercing damage on a failure or half as much on a success.
